“jQuery Mobile, Rails, and Devise”

To start, I recommend reading through Jarod Santo’s excellent introduction to using jQuery Mobile with Rails 3 . It goes through the steps of integrating the mobile framework into a standard CRUD scaffold. However, to make your app both mobile and desktop-savvy, you’ll probably want to do some browser detection like that covered in the Railscasts episode on mobile web apps . Depending on the mobile devices you want to support (jQuery Mobile should eventually support most mobile platforms) you may need to change the regular expression Ryan uses to detect mobile browsers.
